LiteraTracker that developed in Dr. Mullins Lab at University of Washington provides the web service for user to track topic-specific literatures. The interface was organized with journal name, number of literatures related to user's search topic in different time frame (total, last 180, 90, 30 days), which can be linked to NCBI PubMed database for further reference. User can organize the list by adding or removing any journals, and add new search keywords.
